Why Leaving Moss on Your Roof is a Costly Mistake

It is easy to ignore a little green growth on your roofline, but moss acts like a sponge, soaking up massive amounts of rainwater. Because it retains this moisture against your roof tiles, it creates a constant damp environment that accelerates wear and tear.During the colder Kent winters, this trapped water freezes and expands. This process, known as frost damage, can easily crack, lift, or break your clay and concrete tiles. Once the tile integrity is compromised, water ingress becomes a serious risk, leading to damp ceilings and rotting roof timbers.Furthermore, heavy clumps of moss frequently dislodge during high winds and heavy rain. They roll down your roof and straight into your UPVC gutters. Blocked gutters cannot effectively direct water away from your home, leading to overflowing water that damages brickwork and fascia boards. Acting early with professional roof maintenance saves you from these expensive emergency roof repairs down the line.

Why Choose Us for Moss Removal & Roof Cleaning?

Our Safe Roof Cleaning and Soft Washing Process

Every roof requires a tailored approach to ensure the tiles remain protected during the cleaning process. As an experienced roofing contractor, we never use destructive, high-pressure washing methods that can blast the protective coating off your tiles or force water under your breathable membrane.Our proven process starts with a full visual inspection of the roof structure to identify any existing cracked tiles or weak mortar on the ridge. Next, our directly employed staff use specialist profiling tools to manually scrape the thick moss away from the tiles, working carefully to protect the surface.Once the heavy debris is removed, we apply a low-pressure soft washing technique to gently lift away remaining dirt. Finally, we apply a professional-grade biocide algae treatment. This highly effective solution continues to work over the following months, killing off deep-rooted lichen spores and actively preventing moss from returning.

Common Questions About Roof Cleaning and Algae Treatment

Do you use high-pressure washers on the roof?No, we avoid high-pressure washing because it can strip the protective granular finish off concrete tiles, damage older slate, and force water underneath the lap of the tiles into your loft space. We use manual scraping combined with low-pressure soft washing for a safe, thorough clean.How long does the biocide treatment last?Our professional biocide treatment actively inhibits the regrowth of moss, algae, and lichen. Depending on the surrounding environment, such as overhanging trees, the treatment can keep your roof looking clean and moss-free for several years before a top-up is required.Can you fix broken tiles while cleaning the roof?Yes, absolutely.

Roof Cleaning FAQs

Frequently Asked Questions About Moss Removal

Answers to common questions regarding our professional moss removal, biocide treatments, and roof cleaning services provided by Kevington Roofing and Building LTD across Swanley, Sevenoaks, Kent, and Croydon & South London.

Will moss removal damage my roof tiles?

+

When done correctly, no. We avoid high-pressure jet washing which can be too aggressive. By using manual scraping and a soft-wash biocide treatment, we protect the integrity of your tiles while still getting rid of the moss and algae.

How long does it take for a roof to look clean after a biocide treatment?

+

The manual scrape gives you an immediate improvement. The biocide treatment is a "slow-acting" cleaner. It starts working right away to kill spores, and over the next few months, the weather helps wash away the remaining lichen and stains, leaving the tiles looking cleaner and brighter over time.

How often should I have my roof cleaned in Swanley?

+

It depends on your surroundings. If your house is shaded by large trees or is in a particularly damp area of Kent, you might need a check-up every few years. Generally, a professional biocide treatment can keep moss at bay for several years. Regular gutter cleaning also helps keep the roof environment dry.
